Universal underwater enclosure for cameras and camcorders

ABSTRACT

A universal underwater enclosure has a spherical shell having a hollow in which a camera, camcorder, or other device can be inserted, a lens attached to the shell that can be opened to insert a device, and glove assemblies extending into the hollow for manipulation of a device placed therein. The glove assemblies have fingers and not full gloves, reducing the dimensions of the enclosure—thereby minimizing buoyancy. A mounting system attaches to a device&#39;s tripod mount receptor, fixes the device, and allows it to be adjusted in three dimensions. A pressure equalization system relieves stress on the enclosure, which exhibits neutral buoyancy. A flash mounted on the shell operates independently of any device. Modular lens pods replace the lens to accommodate various other lenses. The glove assemblies have perimeter lips secured to the shell by fasteners and a bezel around teardrop-shaped cut-out holes in the shell. The fingers allow access to all of a device&#39;s controls.

BACKGROUND OF THE INVENTION

The present invention relates generally to underwater photographyequipment and SCUBA diving equipment.

There are several classes of waterproof camera housings. Plastichousings are the most common. They make use of external mechanicalbuttons, levers, and dials that correspond to their respective controlson the digital camera. Plastic housings tend to be bulky, and are notideal for out-of-water use. They average from $200 to $500. Theirexpense is largely attributable to their design. These housings oftencontain many parts that must be custom-designed for each camera. Eachtarget camera tends to have a short life span in the market before beingreplaced by a newer, more feature-rich model, rendering the associatedhousing obsolete.

Vinyl bags can be used with a range of cameras and tend to be affordable(ranging from $30 to $200). The stiff vinyl material makes underwateroperation difficult. At depths exceeding 10 feet, water pressure tendsto simultaneously depress the buttons on the camera—a phenomenon thatsometimes actuates the shutter unintentionally or causes the camera tomalfunction.

Metal housings are targeted to professional photographers and those whocan afford their expense. They are usually made for digital SLR stylecameras. Entry into this market of camera housings begins at $1,000, butcan exceed $20,000 for specialized underwater videography equipment.Prices of $2,000 to $4,000 are most common.

One line of silicone skins for camera equipment allows shallow-water useof one specific camera. These designs do not include a glove, and haveno pressure equalization.

Needs exist for improved waterproof and underwater camera housings.

SUMMARY

It is to be understood that both the following summary and the detaileddescription are exemplary and explanatory and are intended to providefurther explanation of the invention as claimed. Neither the summary northe description that follows is intended to define or limit the scope ofthe invention to the particular features mentioned in the summary or inthe description.

In certain embodiments, the disclosed embodiments may include one ormore of the features described herein.

A new universal underwater enclosure has a shell having a hollow inwhich a camera, camcorder, or other device can be inserted and atransparent viewing area in the shell through which photographs can betaken. One or more glove assemblies is attached to the shell andincludes a portion extending into the hollow of the shell. A gloveassembly allows a user to manipulate a device placed therein withoutopening the shell. The portion of the glove assemblies extending intothe hollow of the shell includes fingers, is not a full glove and doesnot encompass a user's entire palm, so that the amount of unused spacewithin the hollow of the shell is minimized, reducing buoyancy.

In one embodiment, a mounting system fixes the position of a device inthe hollow of the shell and attaches to a tripod mount receptor andallows for adjustment of the device position up and down, left andright, and forward and back. A tripod mount adapter can be used to clampto a device body and present a tripod mount receptor for attaching tothe mounting system.

In one embodiment, the shell is spherical. In one embodiment a pressureequalization system is attached to the shell and maintains an internalshell air pressure equivalent to the external water pressure. Thepressure equalization system in one embodiment includes a carbon dioxidereservoir, a high-pressure regulator, and a low-pressure valve thatreleases gas from the carbon dioxide reservoir to increase internalshell air pressure. In some embodiments, an air-restricting orifice isused in lieu of a regulator. Conversely, the system contains a purgevalve that releases excess internal air pressure when the internal airpressure exceeds the outside water pressure (such will be the caseduring ascent from a dive).

In one embodiment, conductive material is incorporated into thefingertip of one or more of the glove assembly fingers, allowing a userto manipulate touch screens that are based on resistive, capacitive, orsurface acoustic technologies, inside the hollow of the shell.

In one embodiment, the enclosure exhibits neutral buoyancy. In oneembodiment a flash is attached to the shell and operates independentlyof any device placed in the hollow of the shell. In one embodiment theflash system includes LED lights and an external button for triggeringthe flash and is powered by an energy storage device.

In one embodiment, modular lens pods replace all or a portion of thetransparent viewing area and accommodate various lenses. In oneembodiment, the transparent viewing area is an optical lens. In oneembodiment, the shell is made of clear polycarbonate plastic.

In one embodiment, one or more hand shrouds cover one or more of theglove assemblies, protect the glove assemblies and provide a rigidexternal surface upon which to grab.

In one embodiment, there are fasteners and a bezel around one or morecut-out holes in the shell and the glove assemblies have perimeter lipsthat are secured to the shell by the bezel and the fasteners. In oneembodiment the cut-out holes are teardrop-shaped. In one embodiment, thecut-out holes are covered and sealed by the glove assemblies, one ormore of the fingers extend into the hollow of the shell at the side ofthe cut-out nearest a front of the shell and the fingers include a thumbthat extends into the hollow of the shell at the side of the cut-outnearest a back of the shell, providing sufficient range of motion to auser to accommodate all of a device's controls.

In one embodiment, clasps secure the optical glass lens to the shell.The optical glass lens is attached to the shell in a hinged manner andthe optical glass lens can be moved to an open position to allow adevice to be inserted into the hollow in the shell through the resultingopening. In one embodiment, an access panel attached to the shell in ahinged manner can be opened to insert a device into the hollow in theshell.

In one embodiment, the fingers consist of two fingers corresponding to auser's index finger and thumb.

A new universal underwater enclosure has a spherical shell having ahollow in which a camera, camcorder, or other device can be inserted, anoptical glass lens attached to the shell in a hinged manner so that theoptical glass lens can be moved to an open position to allow a device tobe inserted into the hollow in the shell through a resulting opening, aclasp securing the optical glass lens to the shell, and one or moreglove assemblies attached to the shell including a portion extendinginto the hollow of the shell, which allows a user to manipulate a deviceplaced therein without opening the shell. The portion extending into thehollow of the shell includes fingers, and is not a full glove and doesnot encompass a user's entire palm, minimizing the amount of unusedspace within the hollow of the shell and reducing buoyancy.

A mounting system fixes the position of a device in the hollow of theshell, attaches to a tripod mount receptor in a device and allowsadjustment of the device directionally—up and down, left and right, andforward and back.

A pressure equalization system attached to the shell includes a carbondioxide reservoir and pressure valve that releases gas from the carbondioxide reservoir to increase internal shell air pressure in order tomaintain an internal shell air pressure equivalent to external waterpressure. The enclosure exhibits neutral buoyancy.

A flash includes LED lights, an energy storage device, and an externalbutton for triggering the flash attached to the shell and operatingindependently of any device placed in the hollow of the shell.

Modular lens pods replace all or a portion of the optical glass lens toaccommodate various lenses. The glove assemblies have perimeter lips,which are secured to the shell by a bezel around one or moreteardrop-shaped cut-out holes in the shell and fasteners. The cut-outholes are covered by the glove assemblies and one or more of the fingersextend into the hollow of the shell at the side of the cut-out nearest afront of the shell. The fingers include a thumb that extends into thehollow of the shell at the side of the cut-out nearest a back of theshell, allowing sufficient range of motion to a user to accommodate allof a device's controls.

These and other objectives and features of the invention are apparent inthe disclosure, which includes the above and ongoing writtenspecification.

DETAILED DESCRIPTION

An improved universal underwater enclosure for cameras and camcorderswill now be disclosed in terms of various exemplary embodiments. Thisspecification discloses one or more embodiments that incorporatefeatures of the invention. The embodiment(s) described, and referencesin the specification to “one embodiment”, “an embodiment”, “an exampleembodiment”, etc., indicate that the embodiment(s) described may includea particular feature, structure, or characteristic. Such phrases are notnecessarily referring to the same embodiment. When a particular feature,structure, or characteristic is described in connection with anembodiment, persons skilled in the art may effect such feature,structure, or characteristic in connection with other embodimentswhether or not explicitly described.

In the several figures, like reference numerals may be used for likeelements having like functions even in different drawings. Theembodiments described, and their detailed construction and elements, aremerely provided to assist in a comprehensive understanding of theinvention. Thus, it is apparent that the present invention can becarried out in a variety of ways, and does not require any of thespecific features described herein. Also, well-known functions orconstructions are not described in detail since they would obscure theinvention with unnecessary detail.

A new kind of “one size fits all” housing for the underwater photographyand videography market is both affordable and capable, beingapproximately the price of a prior art plastic housing but with many ofthe desirable features of metal housings and many additional featuresnot previously available. Most devices have enough mass and displace asufficient amount of air to cause the housing to be neutral ornegatively buoyant. The housing functions properly under either of thesecircumstances. If necessary, an operator decreases buoyancy by insertingweights within the bottom of the housing. With a pressure equalizationsystem, normal operations are possible to at least 100 feet, the legallimit of a recreational diver.

A single housing accommodates everything from the most compact digitalcamera, to large sophisticated digital SLR cameras with massive lenses.In some embodiments the housing works for digital SLR cameras as largeas 132×103×77 mm (5.2×4.1×3 in), which are the dimensions of the NikonD90 camera.

Although a one-size universal housing can accommodate most types ofcameras, different sizes of housings in certain embodiments offer abalance between maximum versatility, accommodating as many differentcameras as possible, and minimum buoyancy resulting from unused interiorspace. A much larger housing allows large video cameras or other devicesto be placed inside.

In some embodiments a spherical housing is made of clear polycarbonateor acrylic plastic using injection molding. A rigid, shatter-resistantmaterial that is anti-corrosive, transparent, and can withstandtemperature changes of 30 to 80 degrees works well for the application.Some parts of the housing, particularly mounting hardware such asscrews, hinges, bezels, springs, and internal latch components, are insome embodiments made of metal having non-corrosive properties. In oneembodiment a ball-shaped housing made of polycarbonate plastic hassilicone gloves and an optical quality glass lens and has a 7.5″diameter.

In alternative embodiments, the gloves are made of a rubber, latex, oranother non-permeable membrane that resists tearing and puncturing andpresents sufficient elasticity to allow an operator to feel the presenceof, and manipulate controls on an electronic device. The lens presentsoptical quality transparency and in some embodiments is polycarbonateplastic. Describing the housing as “spherical” means that the generaloverall shape of the housing as perceived by the human eye is spherical,i.e. ball-shaped. The lens is dome-shaped or flat, and if dome-shapedpossesses optical characteristics that compensate for the distortion oflight caused by the curvature of the dome. The spherical shape addsstrength to withstand water pressure at deep submersion. The sphericalshape is also key in making the housing universal to all cameras. Noother spherical housings exist in the digital camera/camcorder market.

In lieu of mechanical buttons, inward-facing glove assemblies sealed tothe housing, referred to as “gloves”, provide direct access to thecamera controls (see figures). The glove assemblies are typicallylocated on the sides of the housing The gloves are made of thicksilicone rubber or latex or similar material, while an outer gloveshroud is a hard rubber or plastic compound.

The outer shroud functions as a rigid handle when grasping the housingunderwater. For example, one hand can be in a glove, while the otherhand grasps the outer shroud. The hand shroud protects the glove andprovides an external surface upon which to grab, and maintains anaesthetic spherical shape. In some embodiments the shroud is omitted andthe glove establishes the spherical shape on its own. Glove accessaccommodates all fingers. No other housings currently on the marketfeature inward facing gloves for access to camera controls. In oneembodiment, a conductive surface material is embedded in the tip of oneor more fingers of the glove, affecting the electrical field upon whichthe touch screen operates and allowing the camera to be manipulated. Theconductive material may be placed in a dot at the tip of one or morefingers. FIG. 18 is a side view of a universal underwater cameraenclosure's glove assembly showing conductive contacts 43 in the tip ofthe index finger and thumb of the glove 3.

A rigid plastic bezel secures the glove to the housing body along a lipin the perimeter of the glove. Stainless steel screws around theperimeter of the bezel are used to secure the glove to the housing bodyand create a watertight seal. Other attachment mechanisms are possible,but screws are easily removable and allow the gloves to be replaced inthe event of tearing or rot.

When in operation, the interior surface of the glove is exposed towater, but the exterior surface of the glove (which is in contact withthe camera) remains dry inside the housing. Special tear-shaped cutoutson the side of the plastic housing form the opening for the gloves. Theteardrop shape is the result of a comprehensive analysis of variouscameras, and the range of motion that is required to manipulate theminside a spherical housing. The cutouts are designed to provide accessto 3 primary “zones” on a camera. Top-right, where the shutter buttonand telephoto controls are usually located, back-right, where menuoptions and joy-stick style controls are usually situated, and the back,where a touch-sensitive screen may be present.

The cutouts must accommodate at a minimum an index finger and thumb, andmore commonly all 5 fingers. Therefore, the dimensions of the cutout mayrange from 2-6 inches, depending upon the number of fingers to beaccommodated. By allowing the operator's fingers and thumbs into thehousing, the design allows enough range of motion to accommodate all ofthe camera's controls, regardless of the camera model.

Some housing embodiments feature a modular design of “lens pods”. Lenspods are extenders that accommodate a variety of lenses, including wideangle and telephoto lenses. All or a portion of the lens assembly can beremoved and replaced with a larger pod to accommodate different lenses.FIGS. 20A, 20B, and 21 show lens pods. FIGS. 20A and B are sideperspective views of a telephoto lens accessory. Lens 49, in oneembodiment made of glass, is secured with a clamp 51 to an accordionstyle rubber boot 53, which in turn is attached to a ribbed rubber base55 that twists freely, allowing a user to operate a lens inside the lenspod by grasping the rotatable collar 61 and twisting as shown in FIG.20A. When the collar is released, it rotates free of the lens and thebase returns to its relaxed position.

FIG. 21 is a side perspective view of an alternative telephoto lensaccessory where rubber boot 57 is attached to a rotatable collar 61having elastic dimples 59 that grab a lens inside the lens pod and allowthe lens to be operated by rotating the collar 61. The elastic (e.g.rubber) dimples in the collar allow a user to make contact with the lensbody during rotation, and subsequently release contact with the lens.When the dimples are not pressed against the lens, the collar 61 rotatesfreely. The collar is attached to the base 70 with a watertight seam 68,allowing the collar to rotate freely without water entering the lenspod. A watertight seam 66 also joins the collar 61 and boot 57 in someembodiments, allowing the collar to rotate without rotating the boot 57or lens 49.

Various methods are used in various embodiments to extend and retractthe accordion style boot 53, 57 when the lens is extended or retracted.In some embodiments, the extension and retraction are performed manuallyby a user, while in other embodiments a mechanical link between the lensand lens pod automatically extends or retracts the lens pod with thelens. To avoid placing too great a load on the lens, manual extensionand retraction is used, or in some embodiments an automated system thatdetects rotation of the collar or lens and responds by extending orretracting the lens pod appropriately.

A key design element in this housing is the system for equalization ofwater pressure. Some embodiments contain a pressure system thatmaintains an internal air pressure that is equivalent to the force ofthe external water pressure. FIGS. 22 and 23 illustrate a housingpressurization system. An elastic diaphragm 73 (made for example ofrubber or silicone), affixed to the shell of the housing, bows inwardwhen external water pressure 69 exceeds internal air pressure 67. Themovement of the rubber diaphragm 73 actuates a low pressure valve 75that is positioned inside the housing, adjacent to the diaphragm 73. Theactuation of the pressure valve 75 releases gas 85 from a carbon dioxide(CO2) reservoir 81 contained within the housing. Other gases could beused, but for example oxygen is more expensive and less compressiblethan CO2. In some embodiments, the carbon dioxide reservoir issubstituted or combined with an interface to a diver's oxygen-filledscuba tank, or external “pony” bottle (small scuba bottle, often wornstrapped to a leg). The pressurization system in some embodiments isconnected to the scuba tank by an adapter connected to the scuba tankspare line (“octopus”).

A high pressure regulator 77 reduces the amount of gas 85 escaping fromthe CO2 cartridges 81 to approximately 20 psi. Pressure gauge 83indicates ambient internal air pressure. The released air equalizes theinternal pressure 67 of the ball to match the external pressure 69 ofthe water. When the internal and external pressure are equal, thediaphragm 73 returns to its relaxed state, and ceases to depress theactuator on the low pressure valve 75. With internal pressure equalizedto the external water pressure, the gloves function normally andstresses on the shell of the ball are virtually eliminated. The systemcan utilize a commercial off-the-shelf regulator 77 and pressure gauge83.

Purge valve 91 releases excess internal air pressure when the internalair pressure 67 exceeds the outside water pressure 69 (such will be thecase during ascent from a dive). In this case, excess internal airpressure 87 exerts a force on diaphragm 89, moving the diaphragm 89 andactivating purge valve 91 to release gas 93 from the interior of thehousing 63 out into the water 65.

In the embodiment of FIG. 23, movement of the diaphragm 73 moves pushrod 95 to activate low pressure valve 75.

The camera is inserted into the housing by unlatching a clasp andswinging open the front lens assembly or an access panel along a hingedaxis. In one embodiment, the lens assembly includes a lens with a lip,where the lip is sandwiched between two bezels secured to each otherwith screws, which are made of, for example, stainless steel. The camerais secured to the housing via the camera's tripod mount receptor. If acamera does not have a tripod mount receptor (as is sometimes the casein ultra-compact cameras), an optional tripod mount adapter clamps tothe camera body and exposes a tripod mount receptor.

A mounting system on the interior floor of the housing allows foradjustment of the camera position along the X-Y-Z axes (forward andback, left and right, and up and down) so that the camera is positionedas desired (for example with the LCD window and lens aligned with theirrespective windows in the housing). Windows are used in some embodimentsof the housing where less than the entire shell is clear, and also insome embodiments with viewfinder windows that magnify the image in thecamera's viewfinder.

FIGS. 19A and 19B are detail views of a mounting system. Variousmounting holes 47 in the platform 11 allow the camera to be positionedforwards and backwards, left and right, and with riser block 45, havingadditional mounting holes 47, up and down as well. The riser block insome embodiments is wider than it is tall, providing three possibleheight settings—no riser, narrow riser, and tall riser. The holes arenot to scale. The platform 11 snaps into the housing and a latch pops itout for removing the camera and adjusting the mounting system. A screwenters from the bottom of the platform, extends through the tripod mountreceptor, and is secured in the camera's tripod receptor. Once a camerais appropriately positioned in the mounting system, further adjustmentis not typically necessary.

FIGS. 3 and 4 illustrate the glove assembly. In addition to allowingaccess to the camera controls, the glove assemblies minimize buoyancy ofthe housing. Water is permitted to enter the interior of the gloveassemblies.

The housing in some embodiments provides its own flash capability. Theflash is in some embodiments operated independently of camera operation.The flash in one embodiment is implemented with a series of LED lights,which are pop-up or stationary. In other embodiments other types oflights are used. A flash mounted directly on the housing has adisadvantage in that it can cause backscatter, where reflections fromparticles in the water interfere with the picture. For that reason,external flashes are often used that can be directed at the target fromanother angle. In some embodiments the housing includes one or moreports on the top of the housing, or elsewhere, through which athrough-the-lens (TTL) cable, also called a sync cable, can extend. Thissync cable synchronizes an external flash with the operation of thecamera. The sync cable can connect directly through a wired connectionwith the camera to detect camera operation, or can function with fiberoptics by detecting the camera flash.

In one embodiment, the housing has a bulkead for a TTL cable thatactuates external after-market strobes. In one embodiment, a digitalcamera's internal flash is disabled when used in conjunction with thehousing in order to avoid flushing the housing's lens with light andproducing a white haze effect. In other embodiments, a rubber seal orother device is used to contain light from the camera's flash within aconfined area. Some TTL cables are fiber optic and rely on the camera'sflash for a signal, so in some embodiments where TTL cables are used thecamera flash is not disabled. Some existing underwater housings subduethe camera's built-in flash with a silicone-based panel known as aflash-diffuser, and such a diffuser is used in some embodiments. Someembodiments of this housing provide their own flash mechanisms that aretriggered manually by the operator, and remain lit for a period of timeafter activation. This period of time is configurable.

In some embodiments LED lights mounted on the top and bottom of thefront face provide the housing's flash capability. Lights are poweredthrough a battery compartment located within the camera housing. Anexternal, rubberized, water-sealed button functions as the flash triggerbutton. The flash trigger allows the operator to activate the flash fora period of time before going dim. This period of time in someembodiments is configurable. The flash trigger button in one embodimentis positioned on the carrying handle, on the left-hand side of thehousing.

The terms “right-hand side” and “left-hand side” are relative to theback view of the camera. For example, the shutter button of most camerasis on the “right-hand side”. In certain embodiments tailored for smalland medium sized models, only index finger and thumb operation issupported. By allowing the operator's index finger and thumb into thehousing, the design allows enough range of motion to accommodate all ofthe camera's controls. Since every camera is designed for right-handuse, all compact cameras are compatible with this design. In small andmedium housings, the operator's remaining fingers (other than indexfinger and thumb), grasp the outside right-hand edge of the housingbody. This outer edge features a contoured grip (horned-edge). Thecontoured grip and carrying handle provide opposing forces needed tomaneuver the camera housing in an underwater environment.

SLR cameras require more sophisticated control. Therefore, an embodimentfor large models provides a glove that accommodates all digits(fingers). This model features a modular design of “lens pods” extendersthat accommodate a variety of lenses.

Visually, the housing designs convey two messages of importance: qualityand theme. The housing has precise fit and structural rigidity,instilling confidence that the product will not leak, break, or contortwhen submerged. Although there are business applications for thehousings, the look is targeted to a vacationer's lifestyle, using visualdesign queues to reinforce that image and featuring colors (red, yellow,black) and rubber textures that are suggestive of both “Scuba” and“Photography”.

In some embodiments, the inward-facing glove offers sufficient range ofmotion to manipulate the entire right hand within the embodiment.

The elastic gloves, pressure equalization system, and spherical shape ofthe new housing render it much more practical than products in the priorart using a vinyl bag to access a camera's features.

The waterproof camera housing market is mostly targeted to divers, manyof whom were willing and able to pay the high price of an underwatercamera enclosure designed to withstand depths of 130 feet or more. Thesehousings range from $160 (for compact cameras) to over $4,000 (fordigital SLR cameras). The new universal underwater camera housingappeals both to this existing market and to the recreational andadventure photographer who frequently needs to protect a digital camerafrom shallow water submersion and abrasion. The target audience isbroad, offering an affordable alternative to campers, beach-goers, andwater-sport enthusiasts like snorkelers, surfers, kayakers, andfishermen. This housing makes adventure photography affordable.

The existing market for underwater camera housings is a cross section ofphotography and diving—both of which are well established and have apassionate following. The underwater photography sector is growingrapidly and has international and multicultural market appeal. Marketinterest is also emanating from an increase in adventure travel andeco-conscious tourism. People are increasingly interested in nature,exploration, and exotic travel. A natural extension of this interest isto want to create photographs and videos to capture the moment. Most ofthese exotic environments are underwater or otherwise in places wherephotographic equipment is vulnerable to the elements.

Moreover, digital cameras and camcorders are becoming increasinglycapable. The recent introduction of high definition video to camerasallows the amateur photographer to produce captivating video and stillphotos. This allows the amateur photographer access to very capableequipment.

The present universal housing design provides for incrediblemanufacturing efficiency. Instead of having to create a design for eachnew camera on the market, this single solution accommodates all cameras,old and new. Consequently, the housing is extremely price competitive.

Several photographers have emerged as leaders in the field, and, throughviral marketing, are exposing their techniques to the photographer'scommunity at large. Underwater photography is represented in severallarge and well established trade associations including Dive EquipmentManufacturing Association (DEMA) and the Photo Marketing Association(PMA).

The housings will be distributed through, for example, dive shops,cruise lines, beach supply, and photography shops. A key to their appealis that the universal design minimizes the amount of inventory aretailer needs to carry. In the photography market, where digitalcameras become obsolete within a year's time, the idea of a singlehousing that never becomes obsolete is compelling.

The invention is not limited to the particular embodiments describedabove in detail. Those skilled in the art will recognize that otherarrangements could be devised, for example, variously shaped housings,housings for containing various equipment other than cameras, variousarrangements and combinations of the housing parts, etc. While theinvention has been described with reference to specific illustrativeembodiments, modifications and variations of the invention may beconstructed without departing from the scope of the invention.
